These are the symbols which identify the mint's director. These marks can be symbols or letters. Only Belgium, Finland, France and The Netherlands include a mint master mark on their coins. Monaco, Luxembourg and Slovenia have mint master marks corresponding to the mint that produces them. The formal term for this mark is 'Signature mark of the master of the mint'. The mark is also referred to as a 'privy mark'.

The Belgian mintmaster mark had only been used on the 2 euro commemorative issues, prior to 2008.

Monegasque euro coins are minted in Pessac, France and bear the mintmarks of France. Since no Monegasque Euro coin production began in 2001, the French mintmaster mark used for 1999 and 2000 is not present on any of the coins.

Luxembourg has no domestic mint. Luxembourgish euro coins have been minted in three locations around the Eurozone. The mintmarks, mintmaster's marks and national identification letters can be found near the date (for those produced in Netherlands, Finland and France) or in one of the EU stars on these coins (for those produced in France).SEE: Luxembourg

Slovenia has no domestic mint. Slovenian euro coins have been minted in two locations in the Eurozone. The national identifier (for those produced in Finland), mintmark and mintmaster's mark (for those produced in Netherlands) can be found near one of the EU stars on these coins.SEE: Slovenia
